Hi To Make A Long Story Short. I Turn Off My Jb4 N55 E Series For Drive Cycle To Get My Car Get Inspected. At Wot The Car Car Is Getting No Boost And Engine Malfuction Light Came. Thought It Was Vanos Solenoid But When I Turn Jb4 Back On Again Everything Is Back To Normal. Is That The Jb4 Need An Update? Newer Jb4 Have 12 Settings Or 13. Mine Only Goes Up To Setting 11. Thanks

SETTING 0 MAP AT 0 AND AUTOCLEAR OFF. DO I NEED TO TURN BOOST ON FUEL OFF TOO AND EVERYTHING OFF?

Map 0 acts like a stock map with CANbus use. The only real way is to physically remove the JB4.
